沥青混合料复合改性增强剂
详细说明
【Product Introduction】
Asphalt mixture composite modifier enhancer refers to: the road surface paved with asphalt mixture produced by adding ultra-high performance non-rutting asphalt modifier , its anti-rutting performance is more than 15 times that of ordinary SBS modified asphalt mixture , which significantly reduces road rutting, so that the asphalt pavement will not rut and crack under the high-intensity rolling of heavy-loaded vehicles during its service life , and no rutting above 1.0 cm will occur and there will be no rutting cracks on the traffic pavement .
Asphalt mixture composite modification enhancer is a polymer material that is composite-modified using single-component epoxy and reactive tackifying resin. It can be directly added to the mixing tank of the asphalt mixing plant to modify the asphalt, greatly improving the anti-rutting performance of the asphalt mixture.
【Features】
Stable quality and excellent performance
Adding this product to No. 70 road petroleum asphalt can increase the 60 °C dynamic stability of the corresponding mixture to more than 40,000 times / mm and the 70 °C dynamic stability to more than 20,000 times /mm ; at the same time , it has no adverse effects on the low-temperature performance and water damage resistance of the mixture .
The product is externally mixed and easy to use
There is no need to adjust the gradation of asphalt mixture, it can .
[Scope of application]
Asphalt mixture composite modifiers and enhancers can be used to prepare ultra-high performance asphalt mixtures for heavy-load traffic on highways, national and provincial roads, and urban roads , long uphill and downhill sections, urban road bus lanes, heavy-load intersections , airport runways, highway toll stations, and other sections prone to severe rutting and rutting.
【Performance indicators】
Asphalt mixture composite modification enhancer should be an admixture that has been tested and verified to have good road performance. Its performance technical requirements are as follows.

Technical indicators and requirements of composite modifiers for asphalt mixtures
【How to use】
Dosage: If there are test conditions, three different dosages should be measured.The changes in the high temperature performance, water stability performance, low temperature performance and other road performance of the asphalt mixture after the asphalt mixture is composited with a modifier and enhancer are determined comprehensively. When there is a lack of test conditions, the reference range of the dosage is 0.8%~1.0% ;
Add the product directly into the asphalt mixing plant according to the designed dosage;
Units with conditions can use automatic continuous feeders for feeding.
【Packaging and storage】
Packaging
It is packaged in fusible PE bags, usually 25kg/ bag, and can also be customized as needed.
Storage
Store in dry, airtight condition.
【Construction technology】
The use process of the composite modifier for asphalt mixture is convenient and simple. It can be directly added during the mixing process of the asphalt mixture. It can be added by a feeder or manually. If the manual feeding mode is used, it should be added within 10 seconds after the stone starts to be fed.
Dry mix the additives with the mineral material, and the mixing time should be 10 seconds or more;
Add hot asphalt for wet mixing, the mixing time should be 45 seconds or more;
The quality control, storage and transportation of finished mixture shall refer to SBS modified asphalt mixture.
【Engineering Application】
Asphalt mixture composite modifier technology has been successfully applied in many projects:
1. In 2019 , it was applied on the heavy-load traffic section of Nanjing Zhengpu Line. After three years of operation, it has been shown that it has better overcome the history of two repairs per year, and no rutting disease has occurred so far;
2. In August 2022 , the rutting treatment at intersections of Nanjing's 2022 national and provincial road maintenance and repair project;
3. In September 2022 , Huai'an City's 2022 national and provincial trunk road pavement maintenance project;
4. In October 2022 , Huai'an City's 2022 National and Provincial Trunk Highway G344 Road Maintenance and Emergency Repair Project; Changzhou City's 2022 Maintenance and Major Repair Project S232 Rutting Treatment;
5. In November 2022 , Nanjing G205 and Changzhou S265 disaster prevention and emergency repair projects.
